Many cyclist had given me the distance to the top but as I had passed them all, I camped after 80k at 4,500m as I had no idea if it was another 2k or 6k to the top. Four upper body layers and two below could hardly keep me warm when sitting still and eating, so I treasured getting in my sleeping bag at 20.30. Despite two headache pills at midnight I hardly got any sleep, but when I got up at 7.30 my pulse was down to normal....
